Looks like trouble when Openbios tries to build the device up in Name Space? On Sunday, December 17, 2017, 11:25:08 AM EST, Jd Lyons lyons_dj@yahoo.com wrote:

That looks like stuff from a PCI option ROM. But you can't start at 4000020, that's still in the PCI header overhead.
See
https://code.coreboot.org/p/openboot/source/tree/1/obp/dev/pci/fcode-rom.fth
Follow the code in locate-fcode and fcode-image? to find where the code starts. From my recollection, this looks like the FCode is for a card with vendor ID 10de and device ID 0141. It looks like the FCode should start at 4000040, so that's the address you should feel into byte-load.

That "dev" is harmful, it's taking you out of the PCI node, you need to stay inside unnamed node. Don't do that.

If this had worked with fcode-debug? set to true, I think you would normally have gotten the name of the device printed out.
0 > dev /pci ls
This is again taking you out of wherever you had run the FCode.

At this point, you're doing a second execution of the PCI header, and I have no idea what "PCIR" does as FCodes. It undoubtedly got confused and did something dumb.
